I use Ubuntu 16.04 on several machines at work.
On each of them, certain Debian packages are not correctly downloaded (corrupted).
Example with apt-get:
$ sudo apt-get install traceroute

The following packages were automatically installed and are no longer required:
linux-headers-4.4.0-53 linux-headers-4.4.0-53-generic linux-image-4.4.0-53-generic
linux-image-extra-4.4.0-53-generic
Use 'sudo apt autoremove' to remove them.
The following NEW packages will be installed:

As you can see, the file is not correctly downloaded with curl: curl: (18) transfer closed with 1950 bytes remaining to read. wget also does not solve the problem.
Note that through a 4G connection share, the command works perfectly well.
I tried on Ubuntu 16.04 or 16.10 through docker: same problem.
I changed the Ubuntu repository (main, uk, it, etc.): same problem.
I am not the enterprise sys admin so I cannot check what's going on in this (windows) enterprise network.
Something corrupts certain file types, here .deb.
Which work-around could I test?
I finally found a work-around: using an https Ubuntu repository.
This page shows a list of Ubuntu repositories which are accessible through https.
I used https://mirror.vorboss.net/ubuntu-archive/ which worked perfectly well.
In conclusion, I think that my enterprise network is "protected" by a firewall which refuses to let me download certain (always the same, systematically) .deb files. This firewall could make a signature of the new downloaded file, detect it as a "menace" and refuse to send me its last part.
